Ta evropski standard zajema naprave za preverjanje učinkovitosti grelnih naprav z merjenjem parametrov izpušnega plina plinskih grelnih naprav za gospodinjske in komercialne uporabe. Napravo lahko sestavljajo različni funkcionalni moduli, ki se združujejo na različne načine v skladu z različnimi uporabami, pri čemer je mogoče ločeno preskusiti njihovo skladnost s tem standardom. 1. del standarda EN 50379 določa splošne zahteve in je dopolnjen z zahtevami v standardu EN 50379-2 in/ali EN 50379-3. Ta evropski standard določa zahteve za delovanje prenosnih odčitovalnih naprav za zaznavanje posebnih parametrov vnetljivosti izpušnega plina, kot so koncentracija plinastih spojin, temperatura in/ali tlak, za odločanje, ali je potrebno vzdrževanje naprave, in za prilagajanje naprave med vzdrževanjem. Ta evropski standard ne zajema naprav za: – preverjanje naprav, ki za gorivo ne uporabljajo plina, – trajno spremljanje in nadzor emisij in varnosti ter – uporabo v posodah z mednarodno tovorno črto.

Introduction

This European Standard covers apparatus for measuring gas concentrations and other combustion

parameters, as used in the installation and maintenance of heating appliances. It forms a specification for

portable electrical apparatus designed to measure combustion flue gas parameters of heating appliances,

and includes the following parts under the generic title Specification for portable electrical apparatus designed

to measure combustion flue gas parameters of heating appliances:
Part 1: General requirements and test methods;

Part 2: Performance requirements for apparatus used in statutory inspections and assessments;

Part 3: Performance requirements for apparatus used in non-statutory servicing of gas fired heating

appliances.

EN 50379-1 specifies general requirements for the construction, testing and performance of portable spot

reading apparatus, designed to give an assessment of specific combustion flue gas parameters such as

concentration of gaseous compounds, temperature and/or pressure, to check the combustion performance of

heating appliances for domestic residential and commercial applications using commercially available fuels.

EN 50379-2 is for apparatus intended to be used for statutory measurement. In several European countries,

legal requirements exist for the performance of heating appliances. Authorised inspectors use these

apparatus to measure the flue gas parameters, in order to test the compliance with national regulations. Due

to the legal consequences resulting from the measurement there are strict requirements regarding the

measuring uncertainty of these apparatus. Therefore EN 50379-2 includes maximum values for measuring

uncertainty of the apparatus. Tests with real flue gases form a key part of the verification of the performance

of the apparatus for statutory measurement. The measuring uncertainty has to be justified by internationally

accepted methods over the whole measuring range.

EN 50379-3 is for apparatus intended to be used for non-statutory applications. There are reduced

performance requirements, because the apparatus are designed to decide whether maintenance for a gas

fired appliance is required, and for adjusting the appliance during maintenance. There will be no

determination of the measuring uncertainty for the apparatus.

1 Scope

This European Standard covers apparatus designed for checking the performance of heating appliances by

measuring flue gas parameters of gas fired heating appliances for domestic residential and commercial

applications.

The apparatus may consist of different functional modules which may be tested separately for complying with

this standard, and will be combined in different ways according to the different applications. Part 1 of

EN 50379 specifies the general requirements and is supplemented by the requirements in EN 50379-2 and/or

EN 50379-3.

This European Standard specifies the performance requirements of portable spot reading apparatus

designed to detect specific combustion flue gas parameters, such as concentration of gaseous compounds,

temperature and/or pressure, to be used to decide if maintenance for the appliance is required and for

adjusting the appliance during maintenance.
This European Standard excludes apparatus for
– checking appliances using fuels other than gas,
– continuous emission, safety monitoring and control, and
– use in vessels with an international load line.
